Application filed January 6, 1911.

To aZZ 'whom it may Gomera Be it known that I, EDwARD C. Lnwis, a citizen of the United States, residing at Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Latrine-Incinerators, of which the following is a specification.

My invention relates to latrine incinerators, and constitutes an improvement over the apparatus which was described and claimed in my co-pending application, Serial Number 591,824, filed November 11, 1910.

The construction which was described in the last-mentioned application was such that,

the excreta were scraped from the bowl into the furnace or incinerator, where such excreta are burned and the blades of the scraper sterilized. In the construction which forms the subject-matter of the present application the excreta are delivered to the furnace by swinging` inwardly a plate which forms the bottom of the bowl, thus throwing the excreta upon the bed of fuel and sterilizing the movable bottom plate of the bowl. This mechanism is preferably operated by means of the cover, in connection with which an extension is provided, which is connected by means of a link with the movable bottom plate. It will be clear to those skilled in the art that this construction 'has the advantage of great simplicity and little liability for the necessity of repairs.

These and other advantages of my invention will be clearer by reference to the accompanying drawings, which represent a preferred embodiment of my improvements, and in which- Figure 1 is a plan view showing the incinerator or furnace with the bowls connected therewith; Fig. 2 is a Vertical section through one of the bowls, taken on the line 2-2 of Fig. 1, the cover being shown in elevated position; and Fig. 3 is a Vertical section similar to Fig. 2 eXcept thatI the cover is shown as closed.

A'plurality of latrines 10 are connected with a furnace 11, which may be of any desired construction. In the drawings I have shown three latrines; but my invention is equally applicable where but a single latrine or any desirecl number are used. The incinerator 11 has a central opening 12 in Specificaton of Letters Patent.

its top, and on one side is provided with a fire door of the usual construction.

Each of the latrines 10 comprises a bowl 13 which is preferably made integral with the seat 14. The bowl 13 is also provided with a movable bottom plate 15, which is pivoted at 16 and providedwith a shallow central groove 17. The pivotal connections 16 operate within the slots 18 in the sides of the bowl 13. The bottom plate 15 is also supported by means of the lugs 19.

The cover 20 is pivoted at 21 and provided with the extension 22 which is connected with the bottom plate 15 by means of the links 23 and forms the rear side wall of the bowl. l/Vhen the bottom plate 15 is in the position shown in Fig. 2, its upper edge 23a abuts against the downwardly extendlng rib or fiange 24, which is preferably made integral with the bowl 13. The inside of the bowl 13 is in direct communication with the inside of the incinerator 1.1.

Having thus described the construction of the various parts used in my invention, its operation may now be readily understood. VVhen one of the latrines 10 is to be used, the cover 20`is raised and the parts assume the positions shown in Fig. 2, the excreta being caught on the bottom plate 15. Vifhen the cover 20 is closed, the bottom plate 15 is first moved to the right, until the pivotal. connections 16 reach the right-hand ends of the slots 18. As the cover 20 cont-inues to be lowered, the extension 22 is of course correspondingly raised, and the links 23 then operate to 'swing the bottom plate 15 upwardly until itassumes the position shown in Fig. 3. In this way the excreta are' thrown upon the bed of fuel within the incinerator or furnace 11. An eXaminat-ion of Figs. 2 and 3 will demonstrate that when the cover 20 is raised, the opening between the interior of the bowl 13 and the inside of the incinerator 11 is substantially closed by the extension 22, whereas when the cover 20 is closed, the same opening is substantially closed by the bottom plate 15. In this way the access of excessive heat to the inside of ythe bowl 13 is prevented, and also the pasand in this way becomes perfectly sterilized. IV hen the cover 20 is again raised, the eX- tension 22 is of course lowered, thereby lowering the bottom plate 15 until it rests on the lugs 19. On raising the cover 20 still farther, the bottom plate 15 is moved to .the left, forming a close connection between its upper edge 23a and the edge of the flange 24, which preferably has an overhanging bottom wihereby the eXcreta ;are :deposi'ted 'in the furnace, said bottom-actuating means operating to normally -close off the latrine from the furnace a-nd also to automatically remove such closu-re when the bottom ;is actuated, lsubstantially as described.
